cd4017工作原理

cd4017工作原理
CD4017是一种常见的十进制计数器芯片,它可以将输入信号
按照顺序分配到10个输出引脚上。

该芯片是由一个主计数器
和一个辅助计数器组成的。

主计数器用于存储当前的计数值,辅助计数器则用于控制主计数器的计数顺序。

在CD4017工作时,首先要保证RESET引脚的电平为低电平,这样可以将主计数器复位为初始状态。

其次,时钟信号(CLOCK)被输入到CLOCK引脚上,当CLOCK信号的边沿触
发器工作时,主计数器就会根据时钟信号的变化进行计数。

当计数达到10时,主计数器会自动重置为0,并且辅助计数器
会自动加1。

辅助计数器的输出由十个输出引脚(Q0-Q9)表示。

对于每个输
入时钟脉冲,辅助计数器会使得相应的输出引脚(Q0-Q9)变为
高电平,而其他的输出引脚则保持低电平。

这样,我们可以通过检测Q0-Q9引脚的电平变化来实现对输入信号的分配。

需要注意的是,CD4017只能实现十进制的计数,而且它是一
个顺序计数器,即每次只能计数1个单位。

如果需要实现其他进制或者多单位的计数,就需要使用其他的计数器芯片。

通过这样的工作原理,CD4017计数器芯片能够在很多电子电
路中实现各种不同的功能,比如时序控制、信号分配等。

CD4017的原理及应用电路

CD4017的原理及应用电路

CD4017的原理及应用电路一、原理介绍:CD4017是一种CMOS逻辑芯片,由10位二进制计数器和十个输出引脚组成。

它有一个时钟输入引脚(CLK)和一个复位引脚(RST),CLK触发计数器计数,RST用于将计数器复位为0。

当CLK引脚接收到上升沿时,计数器会递增1,同时输出引脚中的一个将变为高电平,其余输出引脚将变为低电平。

二、工作原理:当CD4017复位后,输出引脚0(Q0)为高电平,其余引脚为低电平。

当CLK输入引脚接收到上升沿时,计数器会递增1、输出引脚中的其中一位(从Q0到Q9)将变为高电平,而上一个高电平输出引脚将变为低电平。

每次计数由上升沿触发,从0到9循环,所以接收到10个时钟脉冲时,所有输出引脚都会被触发一次。

三、应用电路:1.LED跑马灯:CD4017常用于驱动LED的控制电路。

一个简单的应用是LED跑马灯电路。

可以将CD4017与LED灯串联,其中CLK接入一个时钟发生器,RST接入复位开关。

每当接收到一个时钟脉冲时,CD4017会将高电平依次传递给LED灯,使得LED灯按照顺序依次亮起。

2.计数显示器:将CD4017与七段数码管连接,可以构建一个简单的计数显示器。

当接收到时钟脉冲时,CD4017会递增1,并将当前计数值的二进制编码通过输出引脚传递给七段数码管,显示相应的数字。

通过适当的编码和解码电路,可以实现各种不同计数方式的显示。

3.触发摇摆器:4.步进电机控制器:CD4017可以用于步进电机的控制。

通过将CD4017的输出引脚与步进电机控制器的输入引脚连接,可以实现步进电机的顺序控制。

每当接收到时钟脉冲时,CD4017会将高电平输出引脚依次切换,从而控制步进电机的运动方向和步数。

以上是对CD4017的原理与常见应用电路的介绍。

CD4017是一种十分常见的分频计数器,具有较高的性能和稳定性,在各种电子设备中都有广泛的应用。

数字电路CD4017的原理及应用电路

数字电路CD4017的原理及应用电路

数字电路CD4017的原理及应用电路数字电路CD4017是十进制计数/分频器,它的内部由计数器及译码器两部分组成,由译码输出实现对脉冲信号的分配,整个输出时序就是Q0、Q1、Q2、…、Q9依次出现与时钟同步的高电平,宽度等于时钟周期。

CD4017有10个输出端(Q0~Q9)和1个进位输出端~Q5-9。

每输入10个计数脉冲,~Q5-9就可得到1个进位正脉冲,该进位输出信号可作为下一级的时钟信号。

CD4017有3个输(MR、CP0和~CP1),MR为清零端,当在MR端上加高电平或正脉冲时其输出Q0为高电平,其余输出端(Q1~Q9)均为低电平。

CP0和~CPl是2个时钟输入端,若要用上升沿来计数,则信号由CP0端输入;若要用下降沿来计数,则信号由~CPl端输入。

设置2个时钟输入端,级联时比较方便,可驱动更多二极管发光。

由此可见,当CD4017有连续脉冲输入时,其对应的输出端依次变为高电平状态,故可直接用作顺序脉冲发生器。

CD4017有两个时钟端CP 和EN,若用时钟脉冲的上沿计数,则信号从CP 端输入;若用下降沿计数,则信号从EN 端输入。

设置两个时钟端是为了级联方便。

CD4017 与CD4022 是一对姊妹产品,主要区别是CD4022 是八进制的,所以译码输出仅有Y0~Y7,每输入8 个脉冲周期,就可得到一个进位输出,它们的管脚相同,不过CD4022 的6、9 脚是空脚。

各种发光方式可按自己的需要进行具体的组合,若要改变彩灯的闪光速度,可改变电容C1的大小。

十进制计数分配器CD4017简介

十进制计数分配器CD4017简介

十进制计数/分配器CD4017简介CD4017是十进制计数/分配器,它有3个输入端,即复位端R、时钟端CP和CP E(也叫EN),CP端为脉冲上升沿有效,CP E为脉冲下降沿有效;它还有10个输出端,即Q0~Q9。

在复位状态时,只有Q0为高电平“1”状态,其它输出端均为低电平“0”状态。

当时钟端输入有效时钟脉冲(CP 端输入上升沿或CP E输入下降沿)时,输出端的高电平在Q0~Q9之间依次循环传递。

CD4017还设有进位输出端CO,当多个CD4017级联使用时该端连接到相邻级的时钟输入端。

CD4017为DIP16脚封装(双列直插封装),各引脚功能见图1,真值表见附表。

这种集成电路在自动控制电路中应用很广泛,是CMOS4000系列数字集成电路中应用率较高的型号之一。

各种报刊介绍的应用电路中经常出现它,本文通过一个实例介绍其应用方法与技巧。

图2所示是一个电子互锁开关电路。

可用于多路信号的切换控制。

图中或非门CD4001的2个门构成键控振荡器,其输出送至CD4017的CP端。

由于振荡器的键控输入端由上拉电阻R1拉至高电平“1”状态,所以在按键SB0~SB9均未按下时振荡器处于停振状态。

十进制计数器CD4017的10个输出端用于控制10个信号通道(这里只画出了控制端口),如果待选信号不足10路,则输出端Q0可空置不用,这样CD4017复位后所有的信号通道均未选中,即接通电源后按一下清零按钮SB,输出端Q0变为高电平,由于Q0端空置,因此没有信号通路被选中。

若欲选中某一路信号,例如受Q5控制的第五路信号,可按下按键SB5,由于按下按键SB5之前Q5端为低电平,所以振荡器的键控端也变为低电平,键控振荡器起振,振荡信号送CD4017的CP端。

因为振荡频率很高(约4.5kHz),在很短时间内(几mS 时间,手还未来得及松开)Q5即由低电平变为高电平,这样受Q5控制的那一路信号即可通过后续电路(未画出)被选中。

同时Q5的高电平反馈到键控端使振荡器停振,Q5的高电平状态被锁定。
